i've seen many people p/p their maf. this changes the calibrations involved, how do you recalibrate it?

also is the calibrating in the maf or the computer? what if you were to buy an aftermarket housing that doesn't have the divider, wouldn't that mess with the calibrating of the system.

how does this all work?

 

do a search for this. there were many discussions debates over this. i ported mine and yes that throws the calibration off of the mass air flow sensor. i dont have a scanner but believe my blms are pegged. IMHO descreening is ok without reprogramming your pcm. if you do the port you should have the pcm redone to adjust for the different readings. it can be done but the stocker flows lots of air anyway.
